Juventus coach Max Allegri was unimpressed after their 3-1 win over Sassuolo.

Paulo Dybala struck a hat-trick, but Allegri was upset with his team's performance.

“Even when we were 2-0 up today, we lost a little concentration," said Allegri. “We shouldn't have conceded.

“It is down to our reading of moments in the match. After 35 minutes of doing well, you shouldn't stretch yourself, you should wait and take the match by your hands.

“We need to work on that, but let's congratulate the boys as well."

Allegri added that despite talisman Dybala having scored two hat-tricks already this season, the playmaker still has much room for improvement.

“He is improving in all aspects of the game. He is very young and has much room for improvement.

“When we go ahead he needs to keep playing with just two touches. When he plays like that he is unstoppable."
